| 中文摘要 |
| 本文研究了玉米麸质铁去除废水 Cr(VI)过程中酸度、流速对去除率的影响以及再生和实验室放大试验等问题.结果表明,Cr(VI)去除率可达99.9%,动态饱和吸附量是27mg/g.实验室放大试验结果满意.用0.3mol·L-1NH3·H2O可以再生.为小规模含铬废水的治理提供了一种价格便宜,操作简单可靠的方法. |
| 英文摘要 |
| This paper introduces a new method for the removal of Cr(Ⅵ) form wastewater by using Fe-modified corn gluten. The experimental results show that the rate of removal can reach 99.9% at pH 2-10 and flow rate of 5-28 ml/min. and the saturated capacity was determined to be 27 mg/g (measured by Cr(Ⅵ)). The results ofenlarged test of true wastewater are satisfactory. The adsorbed Cr(Ⅵ) can be eluated by NH3H2O(0.3M) and then the material can be reused. In view of the properties of the material, the method has the prospect of becoming a cheep and effective one for the treatment of Cr (Ⅵ)-containing wastewater. |
